用Jib配置idea的maven项目中，实现springboot、tomcat 来build镜像

2. Jib+Maven+Springboot 实践代码例子

2.1在maven项目中的pom.xml文件中配置Jib插件

<plugin>
        <groupId>com.google.cloud.tools</groupId>
        <artifactId>jib-maven-plugin</artifactId>
        <version>1.0.1</version>
      </plugin>

pluginManagement & plugins 如果在idea右边不显示插件jib，注意把pluginManagement注释了，就可以正常显示了

2.2 配置详情

1.这里有一个验证直接使用用户名和密码，来替代credHelper使用。验证成功后可以直接从Docker hub或者网易hub.c.163.com上获取官方镜像（依据个人喜好配置对应的auth）

<!--jib 构建插件-->
            <plugin>
                <groupId>com.google.cloud.tools</groupId>
                <artifactId>jib-maven-plugin</artifactId>
                <version>1.0.1</version>
                <configuration>
                    <from>
                        <image>openjdk:alpine</image>
                        <!--直接指定凭证（替代credHelper）-->
                        <auth>
                            <username>${registry_username}</username>
                            <password>${registry_password}</password>
                        </auth>
                    </from>
                    <to>
                        <image>${registry_url}/${project.artifactId}</image>
                        <tags>
                            <tag>latest</tag>
                        </tags>
                &lt;/to&gt;
                &lt;container&gt;
                    &lt;mainClass&gt;com.ecdata.CmpApplication&lt;/mainClass&gt;
                    &lt;!--使用当前时间--&gt;
                    &lt;useCurrentTimestamp&gt;true&lt;/useCurrentTimestamp&gt;
                    &lt;!--容器在运行时暴露的端口--&gt;
                    &lt;ports&gt;
                        &lt;port&gt;8088&lt;/port&gt;
                    &lt;/ports&gt;
                &lt;/container&gt;
                &lt;!--如果私有镜像仓库没有启用https，设置allowInsecureRegistries参数为true--&gt;
                &lt;allowInsecureRegistries&gt;false&lt;/allowInsecureRegistries&gt;
            &lt;/configuration&gt;
            &lt;!--绑定jib:build到 Maven生命周期，例如package--&gt;
            &lt;executions&gt;
                &lt;execution&gt;
                    &lt;phase&gt;package&lt;/phase&gt;
                    &lt;goals&gt;
                        &lt;goal&gt;dockerBuild&lt;/goal&gt;
                    &lt;/goals&gt;
                &lt;/execution&gt;
            &lt;/executions&gt;
        &lt;/plugin&gt;

已绑定jib:build到 Maven生命周期package，所以直接运行package

2.3 验证生成好的镜像：

sai:~ ws$ docker images | grep 31.16.14.55/szy/cmp
31.16.14.55/szy/cmp                           latest              70440c0ad660        6 minutes ago       213MB
sai:~ ws$ 

2.4 push镜像到镜像仓库：

sai:~ ws$ docker push31.16.14.55/szy/cmp
